Is Benzene, 1- (chloromethyl) -3 (or 4) - (2- (trimethoxysilyl) ethyl) - chemically stable?
Benzene, 1 - (chloromethyl) - 3 (or 4) - (2 - (trimethoxysilyl) ethyl) This substance has relatively stable chemical properties. Looking at its structure, the part containing the benzene ring has a conjugated system, which makes this part of the chemical properties relatively stable and not prone to active reactions such as addition. And 1 - (chloromethyl) group, the chlorine atom has a certain electronegativity, which makes the group have a certain activity, but its activity is still controllable compared with many active groups. Furthermore, in 3 (or 4) - (2 - (trimethoxysilyl) ethyl), the trimethoxysilyl part is relatively stable in silica bonds, and the presence of trimethoxy groups further enhances the stability of this part.

What is the preparation method of Benzene, 1- (chloromethyl) -3 (or 4) - (2- (trimethoxysilyl) ethyl) -
The method of preparing 1 - (chloromethyl) -3 (or 4) - (2 - (trimethoxysilyl) ethyl) benzene can be done according to the following steps.
First take trimethoxysilyl ethanol, place it in a reaction kettle with a suitable base, such as potassium carbonate, etc., add an appropriate amount of organic solvent, such as N, N - dimethylformamide (DMF), and stir well. The action of the base is to deprotonate the hydroxyl group of trimethoxysilyl ethanol and enhance its nucleophilicity.
Second, halogenated benzyl, that is, benzyl halogen containing chloromethyl, is slowly added to the above reaction system. The chloromethyl group of this halobenzyl is highly active, and the oxygen anion after deprotonation of trimethoxysilyl ethanol can undergo nucleophilic substitution reaction with it. During the reaction, the temperature should be controlled in a moderate range, such as 60-80 ° C, and the reaction should be fully stirred for a few times.
After the reaction is completed, the excess alkali is quenched with water, and then the product is extracted with an organic solvent such as ethyl acetate. The extract is dried with anhydrous sodium sulfate. After removing the sodium sulfate, it is distilled under reduced pressure to remove the organic solvent to obtain a crude product.
The crude product can be purified by column chromatography, eluted with a suitable eluent, such as a mixture of petroleum ether and ethyl acetate, in a certain proportion, the fraction containing the target product is collected, and then the eluent is removed by reduced pressure distillation to obtain pure 1 - (chloromethyl) -3 (or 4) - (2 - (trimethoxysilyl) ethyl) benzene.
This preparation method, through various steps, controls the reaction conditions to obtain the desired product.
